The Vikings are doing some forensic accounting on Adrian Peterson's rushing statistics, hoping to discover nine extra yards in the couch cushions that would allow him to break Eric Dickerson's 1984 single-season record of 2,105 yards.

The exercise is a long shot because each week the NFL and its official statistician, the Elias Sports Bureau, review discrepancies in the numbers, according to league spokesman Greg Aiello.

But the Vikings are going to scour for them, anyway.

"Yeah, if we can find those hidden yards, we would do it," Frazier said Monday, Dec. 31. "They have different people who will be doing that, but we'll be doing our own homework, as well. If we can find nine yards, we're going to find them."

Peterson gained 199 yards on a career-high 34 carries Sunday. But he also had four runs for no gain and five that netted minus 8. His 2,097 yards are the second-most in NFL history, and Peterson vowed to continue stalking Dickerson in 2013.
